Jan. 24, 1956 J. T. HUGHES FLUSH VALVE ASSEMBLY Filed Oct. 2, 1953 INVENTOR. A i645 7. HUGHES United States Patent FLUSH VALVE ASSEMBLY James T. Hughes, West Davenport, N. Y. Application October 2, 1953, Serial No. 383,797

1 Claim. (Cl. 4-57) This invention relates to improvements in flush valve closets for toilets and more particularly to an improved flush valve assembly.

The principal object of the present invention is to provide a flush valve assembly, which is an improvement on the old Douglas type of flush valve, and serves to eliminates the usual flush valve and lift wires, which so frequently become out of alignment and cause sticking and inoperativeness of the valve element.

Another object of the invention is to provide an improved flush valve assembly, which is not only positive acting but not susceptible to the ready development of defects.

Still another important object of the invention is to provide a flush valve assembly, which is no more complicated than the present day types of valves on the market and yet is more positive acting and durable in use.

These and various other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawing:

Figure 1 is a fragmentary side elevational view, showing the valve in closed position.

Figure 2 is a front elevation of the structure shown in Figure 1.

Figure 3 is a top plan view.

Figure 4 is a bottom plan view of the structure shown in Figure 3.

Figure 5 is a fragmentary and sectional view showing the valve ball in elevated position.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral denotes the usual flush line head fitting which is threaded as shown in Figure 1 and this has a head portion 11 which serves as a seat for a flush valve ball 12.

Numeral 13 denotes a conventional overflow tube which is in connection with the head structure 10 and it is upon this tube 13 that the present invention generally referred to by numeral 14 is mounted.

The present invention consists of a collar 15, adapted to embrace the tube 13 and this collar 15 has an outstanding threaded barrel 16 for receiving a set screw 17 that can be threaded inwardly to bite against the overflow tube 13.

Secured suitably to the tube 16 is a bridge 18 having upstanding end portions 19, 19, through which a shaft 20 is disposed. One end of this shaft is bent laterally as at 21, while the other end may be an eye or a head 22, these end portions passing through the flanges 19, as is apparent in Figures 3 and 4.

The shaft 20 also passes through depending arms 23, 23 which'are aflixed to medial portions of the leg portions 24, 24 of a U-shaped rocker 25, the bite portion of which is provided with an extension 26 having an opening therethrough and through this opening is disposed a rod 27, the lower end portion 28 of which is threadedly disposed into the usual threaded receiving portion of the conventional valve ball 12, while its upper portion has an eye 29 to which a pull chain 30 connected to the usual rocker 31 is attached.

A weight 32 is adjustable on one of the leg portions 24 of the U-shaped rocker 25 and can be secured in place by a set screw 33.

It can be seen that through proper testing, that the weight 32 can be odjusted to the desired position by pulling on one of the leg portions 24 of the rocker 25. It can be seen that there is no sliding action of the rod 27 and that there is no chance of anything coming out of alignment. There is simply the rocking action of the U-shaped structure 25.

When the rocker 31 is actuated, a pull is exerted on the chain 30 and also on the flush ball 12, to the end that the ball is elevated so that flushing operation will take place in the toilet bowl. Obviously the ball will return to seated position so that the flush tank will refill when the desired lowering of the water level in the tank takes place.

While the foregoing description sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention what is claimed as new is:

In a toilet flush tank including a flush seat and a valve ball for disposition thereon and an overflow tube adjacent thereto; a pivoted structure, a riser afiixed to said ball and to said pivoted structure, said riser being provided with means whereby the same and its ball can be lifted, said pivoted structure being composed of a clamp on the overflow tube and an elongated structure provided with a leg pivotally secured to the clamp structure, said elongated structure being in the form of a rigid U-shaped yoke embracing said overflow tube, said U-shaped yoke being provided with an extension at its bite portion and having an opening for receiving the riser, said extension having a set screw adapted to engage said riser, and an adjustable weight on one of the leg portions of the U-shaped yoke.
